Legal Tender is the first publicly accessible online
tele-robotic laboratory. Remote viewers are presented with a pair of purportedly
authentic US$100 bills. A remote viewer can participate by giving up their anonymity
and agreeing to accept full responsibility for their actions. They are furthermore
reminded that it is a Federal crime to deface US currency.

Title 18, Section 333:

Mutilation
of national bank obligations

Whoever mutilates, cuts, defaces,
disfigures, or perforates, or unites or cements together, or does any other thing to any
bank bill ...shall be fined or imprisoned.

Users are then given exclusive access to a small
portion of the bill (see square on bill pair above) along with a high resolution magnified
view (see image on top right above). The participant can then choose to perform an
experiment on their area of the bill.

After selection, the experiment it performed via a
remote robotic system and the results shown. A puncture test is shown at the top of
the page and a thermal test below.
